Isotopic evidence for the different origins of the Tulum valley groundwaters (San Juan, Argentina).

Stable isotope and tritium analyses were used to improve knowledge of the origin of groundwater in the Tulum valley, San Juan province, Argentina. Groundwater is mainly recharged by the San Juan river, which originates in the high Cordillera of the Andes, and is consequently depleted in isotopic con...
